Retaining Walls in Fresno & Clovis, CA

Slope sliding into your patio? Soil washing out every winter when the rains finally hit? A bare, awkward grade keeping you from using half your yard? A well-built retaining wall solves all of it. Longhorn Landscapes designs and builds retaining walls across Fresno, Clovis, Madera County, and Santa Clara County — segmental block, poured concrete, natural stone, and engineered tiered systems. We build walls that drain properly, stand straight for the long haul, and actually look like part of your landscape.

What retaining wall construction involves

A retaining wall is a structural system, not a stack of blocks. Done right, it manages soil pressure, water, and gravity all at once. We start with a site evaluation: how much grade change you’re holding back, what the soil is like (Central Valley clay loam behaves very differently from decomposed granite on hillside lots in Santa Clara County), and how water moves across the property.

From there we excavate a proper footing trench, compact a base of crushed aggregate, and set the first course dead-level — that bottom course is what determines whether the wall is still straight in twenty years. We build up using SRW (segmental retaining wall) block from manufacturers like Belgard, Keystone, or Calstone, poured concrete with rebar, or natural stone depending on the look you want. Behind every wall we install drain rock and a perforated drain line tied to daylight, because trapped water is what blows walls out during wet winters. Taller walls (typically over 3–4 feet) get geogrid reinforcement tied back into the hillside, and anything over 4 feet gets engineered and permitted per California code.

Why Longhorn Landscapes for retaining walls

• Licensed and insured California landscape contractors who build walls to code, including engineered drawings and permits when the wall height requires them
• Proper drainage on every job — drain rock, filter fabric, and perforated pipe tied to daylight, not just blocks against dirt
• Geogrid reinforcement on taller walls so they stay plumb under San Joaquin Valley clay soil loads
• Wide material selection: Belgard, Keystone, Calstone SRW block, poured concrete, natural stone, and stacked boulder walls
• We integrate walls with the rest of your landscape — steps, lighting, planters, paver patios — so it looks designed, not bolted on
• Clear written estimates with line items, not vague lump-sum guesses

Our retaining wall process

1. Site visit and measurement. We come out, walk the property, measure grade changes, look at soil and drainage, and talk through what you’re trying to accomplish.
2. Design and material selection. We show you block, stone, and finish options and sketch the wall layout — including steps, curves, and any tiered sections.
3. Written estimate. Line-item pricing for excavation, base, block, drainage, backfill, geogrid, and cleanup. No surprises mid-project.
4. Engineering and permits if needed. Walls over 4 feet (measured from footing to top) get stamped engineering and a city or county permit before we dig.
5. Excavation and base prep. We dig the footing, lay compacted aggregate, and set a level first course.
6. Build, drain, backfill. Wall goes up course by course with drain rock and perforated pipe behind it, geogrid on taller sections, and properly compacted backfill.
7. Cap, cleanup, and walkthrough. Caps installed, site cleaned, and we walk the finished wall with you before final payment.

What retaining walls typically cost

Retaining wall pricing depends on a handful of real variables: wall height and length, the block or stone you choose, how much excavation is required, soil conditions, whether geogrid reinforcement or engineering is needed, and access to the work area (a backyard you can only reach through a side gate adds labor). A short 18-inch garden wall in standard SRW block is a very different project from a 5-foot engineered wall holding back a hillside.

Estimates range based on those factors, and we give you a clear written quote after the site visit so you can see exactly what’s included — base prep, drainage, caps, and cleanup — versus what isn’t. For an honest number on your specific wall, request an on-site estimate.

FAQ

How tall can a retaining wall be without a permit in Fresno or Clovis?
Generally, walls up to 4 feet (measured from the bottom of the footing to the top of the wall) that aren’t supporting a surcharge can be built without engineered plans. Anything taller, or any wall supporting a driveway, pool, or structure above it, needs engineering and a permit. We handle that paperwork for you.

What’s the best material for a retaining wall in the Central Valley?
Segmental block (SRW) is the workhorse — durable, good-looking, and it handles our hot dry summers and occasional heavy winter rain well. Poured concrete is strongest for tall or load-bearing walls. Natural stone and stacked boulders look beautiful for garden-scale walls. We’ll recommend based on height, budget, and the style of your home.

Do retaining walls really need drainage behind them?
Yes — and this is where most failed walls fail. Water trapped behind a wall multiplies the pressure on it dramatically. Every wall we build gets drain rock, filter fabric, and a perforated drain line routed to daylight.

Can a retaining wall double as seating or a planter?
Absolutely. Short walls at 18–24 inches make excellent seat walls around patios and fire pits, and we regularly build tiered walls that work as raised planters. Plan it during design and it integrates cleanly with the rest of the yard.

How long does a retaining wall take to build?
A typical residential wall under 50 feet takes about 3–7 working days from excavation to cleanup. Larger or engineered walls take longer, especially if permitting is involved.

Will you tear out my old failing wall?
Yes. Demo and haul-off of an existing wall is a common line item on our estimates. We’ll inspect the failure cause so the replacement doesn’t repeat it.
